Magnetic properties of NdRu2Si2 revisited

Magnetic properties of ternary NdRu2Si2 are analyzed according to resistivity and specific heat studies at very low temperatures. The compound exhibits two magnetic transitions at 9 and 23 K. The latter is the Néel point, whereas the former one was attributed to a change of magnetic ordering from antiferromagnetic to a complex phase with predominant ferromagnetic component. The specific heat measurements reveal an enhancement of electronic specific heat coefficient γ = 86 ( 1 ) mJ/mol K 2 . The Debye temperature was estimated based on resistivity studies to be 273.1(5) K.
